Winema / NDO2438-6R

Winema (NDO2438-6R) is an early maturing,
round to oval, red-skinned clone suitable for table use. It
produces lower total yields than Red LaSoda and Dark Red Norland but
similar marketable yields with a higher percentage of small,
high-value tubers, and significantly fewer culls.
Winema tubers are round to oval,
seldom exhibit growth cracks or rough shape common to Red LaSoda and
Dark Red Norland, produce uniform bright skin color that does not
fade in storage, and have shallow eyes compared to Red LaSoda. The
tubers have lower specific gravity than Dark Red Norland and Red
LaSoda. Internal defects, including hollow heart and brown center,
and external growth cracks seldom occur.

Winema vines mature slightly
earlier than Red LaSoda. Vines are sensitive to metribuzin injury.
It is very susceptible to PVY and foliar PVY symptoms are very
difficult to detect visually. It is also susceptible to most fungal
diseases. In testing at Corvallis, Oregon,
Winema experienced much less foliar and tuber late blight
infection than most selections included in the trial. This was
thought to be due to the maturity of the vines at the time of
infection. Winema is susceptible to
corky ringspot caused by tobacco rattle virus. It is moderate
susceptible to Fusarium dry rot.
